Description

Feeding identical arrays into ArrayUtility::arrayDiffAssocRecursive() results in a non-empty difference.
If the input arrays are identical it returns the whole nesting structure of array, but no real values.

$a = [ 'foo' => [ 0 => 'a'  ] ];
$diff = ArrayUtility::arrayDiffAssocRecursive($a, $a);

$diff === [ 'foo' => [] ];
